This research paper generally relates psychology to teaching; specifically, behavior shaping to curriculum planning. Reports are cited that emphasize operant learning as a means of behavior modification. In this instance, the teacher provides a favorable learning situation and arranges environmental factors to increase or decrease the frequency of certain responses. Implementation of operant learning is achieved through programmed instruction. The principles of this instruction are as follows: a) reward as a motivation for learning, b) learning in small steps, c) active participation in learning, d) learning with few or no errors, and e) learning at one's own pace. Results are reported that reinforce the use of programmed instruction with mentally retarded andemotionally disturbed children. Recommendations for research design specifications are made. Five pages of references are included. (BRB)
